Anyone ever play frisbee golf? Throw a frisbee through a forest 3 or 4 times until you reach the "hole"... Kinda fun, but I lost my frisbee the other day, and they cost money, so I figured "Why can't they put little devices into the disc that sound off from a page?" Surely there is commercially viable
technology to be able to include such sounding devices without impeding the flight of the disc much. Same goes for golf balls. Sure, the new balls/discs wouldn't be approved for professional play, but who the hell plays sports professionally anyway?

[world], not a bad idea. I knew they had those out... But, frisbee gold discs are different, with all sorts of weight standards and such, I want to follow those guidelines. As for golfballs, I'd love to see this baked, but haven't found it. Yet.

Maybe if it just continually made a chirping sound using a small photo battery (the disc kind). Much simpler. In fact they could be sold as add-ons to Frisbee's today; just stick them in the underside center.
